Maine Man Hoping for Safe Return of Mother From Nepal

A woman from Augusta, Maine, is still unaccounted for after a 7.8 magnitude earthquake devastated the Kathmandu region Saturday.

Dawn Habash, 57, was hiking the Tamang Heritage Trek in the Langtang region by herself. Her family last heard from her on April 17.

"She's an incredibly independent woman," said her son, Khaled Habash, who is a Portland business owner. "She's been traveling the world by herself since was 19. So she's strong willed. She'll pull out of it, wherever she is. There's no doubt."

Habash was scheduled to complete the trek and fly out of Nepal this Wednesday.

"Wednesday is my internal worry barometer," said Khaled.

Her family is sharing her photograph and information online, hoping another hiker might have seen her on the trail and can confirm she is alive. They have posted on a Facebook page called "Strictly Missing Person only - Nepal Earthquake 2015."

In the post, her son writes: "We are very worried about her and fear she may be hurt and needing assistance...She has trouble with her knees time to time. She doesn't have a cell phone with her. "
